如何使用熊猫获取雅虎金融指数中的组件列表？

Question

So im trying to get data from multiple stocks from yahoo finance and write it to excell. The problem is at the moment i have to hardcode the stocks in question. and currently i would like to download the information from all 25 stocks in the C25 index (^OMXC25) or potentially other indexes. so therefore i would like to know how i can acces the components list and retrieve these and then download each of them. The current code i use to get each is as follows:

import pandas as pd
import pandas_datareader as pdr
import datetime as dt

download_source = (r'C:\Users\SKlin\Downloads\OMXC25.xlsx')

start = dt.datetime(2010,1,1)
end = dt.datetime.today()

writer = pd.ExcelWriter(download_source, engine ='xlsxwriter')

#GN Store Nord
dfGN = pdr.get_data_yahoo('GN.CO',start,end)
dfGN.to_excel(writer, sheet_name='GN.CO')       

#Vestas Wind systems 
dfVestas = pdr.get_data_yahoo('VWS.CO',start,end)
dfVestas.to_excel(writer, sheet_name='VWS.CO')     

writer.save()

This saves the data just fint, but with 25 stocks it's doable, but seems tidious to do with index with 500 stocks.. Plz help.

Answer 1

If you can get a list of all symbols:

stocks = ['GN.CO' , 'VWS.CO']
for stock in stocks:
    dfGN = pdr.get_data_yahoo(stock ,start,end)
    dfGN.to_excel(writer, sheet_name=stock )  

Answer 2

Use beautiful soup to scrape a list of the ticker names from wiki:

Then just iterate through them.
